However I don't think its wise to open another dice site, why? Because the market is currently saturate with them. A few days doesn't go by without a new dice site popping up. If you want to compete you will need to be creative and think of something new besides your common choices there. Maybe some type of PacMan gambling game that you can make provably fair and cheat-proof. That would get many people interested since its something new.
not only is it easy to learn but it doesn't require any special skills or analysis as well as any possibilities you can take part in this game if you have money to bet because this game is based on 100% luck.
